Physical, Data Link, Network Layers, Management Integration System Essay

A network interface card is already present in the computers. The purpose of the network card is to enable the computers to connect together using a protocol in order to transfer packets of data. In order to connect the computers, a form of connection is required that links the computers. In this case the form of connection used will be ethernet (Science - Opposing Views, 2014).

In the Network Design Paper I will explain how the University has recently leased a building in Adelphi, Maryland. The measurements of the University is 240 feet long, 95 feet wide and 30 feet tall and broken down to two different floors. This University will be used for education purposes of course, the facility will be made of six instructional labs, seven offices, library, five classrooms, a student lobby and a computer lab. There will be a server room on each floor. The purpose of this paper is to explain the design of the networks in this building. The student accessed computers will be set up on a separate network than the network that they staff will be using.

In this report I will evaluate the different formats by giving the benefits and limitations of using the Web, Multimedia (CD’s, DVD’s and so on.), Interactive T.V and Mobile Devices as formats for interactive media products. Each benefit and limitation will be explained with some examples for each format of interactive media products, finally I will give a summary and conclusion for all the formats at the end of the report.

1: Physical layer: The purpose of the physical layer is it deals with the hardware components, like cads and cables for sending and receiving data of a carrier.

Doug Allred was Vice President of Customer Advocacy organization of the Cisco’s corporation. This organization was erected to consolidated all functions that directly touched the customer but sales to provide high-quality customer service. Since August 2001, the IT market turned down and brought severe challenges to Cisco as the company had to lay off 18% of its employees and reorganized its structure, transforming from decentralized organizational structure with three business units to centralized organization. However, these changes stabilized the volatile situation of the economy but threatened Cisco’s customer focus, a

7. What is the piece of hardware that allows a device to physically access a network?

1. Application (in terms of cabling infrastructure): The application layer is the OSI layer closest to the end user, which means both the OSI application layer and the user interact directly with the software application. When determining resource availability, the application layer must decide whether sufficient network or the requested communication exists.. (OSI_model#Layer_7:_application_layer)

Uses a modem which can provide both wired and wireless connections for a number of devices

You will discover different network topologies and different types of networks: LANs, WANs, and internetworks (internets). The concept of switching is discussed to show how small networks can be combined to create larger ones. You will learn about the Internet: its early history, the birth of the Internet, and the issues related to the Internet today. This module covers standards and standards organizations.

When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.

The proposed network is designed to serve DesignIT which consist 56’x36’ office space, 4 cubicles, 1 office, 1 server room, 1 receptionist desk and 1 conference room.

The networking of the system is recommended after a system study and the fact that there has been a 100% expansion of the demand for the system- from 5 to 50 have been noted. It is also shown that as of now there are machines that are stand alone with windows 7 operating system. The task is to provide a network connectivity that would provide direct connections between the employees, and be centralized in the operation. This essentially requires the creation of a network. This means that all the computers must be installed with a network card and this would be the case with windows 7. The question then comes is if there must be windows networking or use other protocols. We can also partly use the most modern practical solutions.

Note to instructor: An alternate answer could be a single large LAN for the entire headquarters, interconnected via a WAN to the field offices.

Ideally, each local office would integrate its computers with a LAN, so that all employees would be able to share information, and resources such as printers. In case there are multiple buildings in an office (like in the corporate office), each building would have its own LAN, and the LANs could be connected by a Backbone Network.
